Portion control is a fundamental strategy in managing obesity, as it helps individuals regulate caloric intake. Many people underestimate the number of calories they consume due to large portion sizes, which can lead to overeating and weight gain. By educating individuals on appropriate portion sizes and promoting mindful eating, portion control can reduce excessive calorie consumption. Techniques like using smaller plates, measuring food, and being aware of hunger cues help people maintain a balanced diet and prevent overeating. In combination with physical activity and healthy food choices, portion control is an effective tool in achieving and maintaining a healthy weight.
